spring boot + Prometheus + Grafana 实现项目监控

news 2025/4/17 8:19:12

一、引入依赖

<dependencies><!-- Spring Boot Starter Actuator --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-actuator</artifactId></dependency><!-- Micrometer Registry for Prometheus --><dependency><groupId>io.micrometer</groupId><artifactId>micrometer-registry-prometheus</artifactId></dependency>
</dependencies>

二、ymal配置

# 配置actuator监视器的全部监控端点打开
management:endpoints:web:exposure:include: "*"endpoint:prometheus:enabled: truehealth:show-details: alwaysmetrics:export:prometheus:enabled: true # 启用Prometheusspring:application:name: easy-brilliant

三、配置数据格式转化

package easy.brilliant.configuration;import io.micrometer.core.instrument.Clock;
import io.micrometer.core.instrument.MeterRegistry;
import io.micrometer.prometheus.PrometheusConfig;
import io.micrometer.prometheus.PrometheusMeterRegistry;
import io.prometheus.client.CollectorRegistry;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.actuate.autoconfigure.metrics.MeterRegistryCustomizer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;@Configuration
public class PrometheusConfiguration {@Beanpublic CollectorRegistry collectorRegistry() {return new CollectorRegistry();}@Beanpublic PrometheusMeterRegistry prometheusMeterRegistry(PrometheusConfig config, CollectorRegistry collectorRegistry) {return new PrometheusMeterRegistry(config, collectorRegistry, Clock.SYSTEM);}@BeanMeterRegistryCustomizer<MeterRegistry> configurePrometheus(@Value("${spring.application.name}") String name){return (registry -> registry.config().commonTags("application",name));}}

四、安装并配置Prometheus

下载地址：https://prometheus.io/ （下载最新版）我的csdn地址：https://download.csdn.net/download/weixin_42172472/90579623

prometheus 配置：

# my global config
global:scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.# scrape_timeout is set to the global default (10s).# Alertmanager configuration
alerting:alertmanagers:- static_configs:- targets:# - alertmanager:9093# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:# - "first_rules.yml"# - "second_rules.yml"# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:- job_name: 'easy-brilliant'metrics_path: '/actuator/prometheus'static_configs:- targets: ['localhost:8047'] # 使用你的Spring Boot应用程序的实际主机和端口替换
